An outbreak of food-related illness, such as E. coli-tainted spinach, often leaves food safety experts scratching their heads over the source of the contamination.
Thanks to a new computer model developed by researchers at the University of Florida, Wageningen University and the University of... Read More
Yale University researchers have found very large RNA structures within previously unstudied bacteria that appear crucial to basic biological functions such as helping viruses infect cells or allowing genes to "jump" to different parts of the chromosome.
These exceptionally large RNA molecule... Read More
Scientists are reporting the first identification of substances involved in the Jekyll-and-Hyde transformation that changes harmless marine bacteria into killers that cause "coral bleaching."
Researcher Dan Bearden and colleagues note that bleaching already has destroyed up to 30 percent of t... Read More

Researchers from the University of Georgia College of Veterinary Medicine have made an "unexpected" dual discovery that could open new avenues for treating Ichthyophthirius multifiliis, or "Ich," a devastating single-celled protozoan parasite that commonly attacks freshwater fish.
With the ai... Read More

The National Institutes of Health said Wednesday that it had approved 13 new human embryonic stem cell lines for use by federally financed researchers, with another 96 lines under review.
The action followed President Obama’s decision in March to expand the number of such cell lines beyond th... Read More
Whether you are making lunch for work, school or a summer picnic, knowing what food to pack and how to prepare it can be the difference between enjoying your day or going home sick. From recent peanut butter and pistachio nut recalls to E. coli outbreaks associated with hamburger patties, peo... Read More
Multiple independent associations between rhizobiales and herbivorous ants provides strong evidence that symbiotic bacteria have facilitated the evolution of nectar and exudate-feeding life histories in ants and their radiation into otherwise inhospitable rainforest canopy habitats, providing a ...

A research team at Johnson Space Centre in Houston has been re-examining a meteorite that hit Antarctica 13,000 years ago, and found the most compelling... Read More
The World Health Organization is now advising health care professionals to start patients with HIV on antiretroviral drugs earlier in the course of their infection, as part of new agency guidelines announced Monday.
The new recommendations will likely result in more patients worldwide obtaini... Read More
Three papers scheduled for publication in the January issue of the Journal of Hospital Infection suggest that copper might have a role in the fight against healthcare-associated infections.
In a busy Birmingham teaching hospital, researchers swapped a conventional toilet seat, tap-handles and... Read More
For the first time, DNA tools have successfully pinpointed the geographic origin of shark fins sold dried in markets to satisfy the demand for shark fin soup, a Chinese delicacy.
Using CSI-like genetic methods, scientists have traced scalloped hammerhead shark fins from a burgeoning Hong Kong... Read More

New swine flu infections continue to drop across the United States, confirmation that the pandemic’s fall wave has peaked, according to figures posted online Monday by the Centers for Disease Control and Prevention.
But the number of children and teenagers killed by swine flu is still rising.... Read More
Federal food safety scientists are waging biological warfare to combat salmonella in tomatoes.
Scientists with the Food and Drug Administration's Center for Food Safety and Applied Nutrition are studying naturally occurring bacteria that can fight the bacteria that causes salmonella and to ke... Read More
A team of scientists from The Forsyth Institute, the University of Connecticut Health Center, the CDC and the Wadsworth Center, have used state-of-the-art technology to elucidate the molecular architecture of Treponema pallidum, the bacterium which causes syphilis. The previously unknown detaile... Read More
Viruses of soil bacteria (phages) evolve to improve their ability to infect the bacterial hosts that surround them. This is shown in a new study by Dutch researcher Michiel Vos, published in the journal Science. Phages appear to be better able to infect bacteria from the same small soil sample t... Read More
Molecular biology for years meant breaking down living cells to their smallest component parts, the genes and proteins that govern what a cell does. But a list of parts tells only so much. To understand how living cells really work, biologists are now trying to visualize how the parts are assemb... Read More
A new drug-resistant strain of bacteria has emerged in the last decade in Africa and is causing unusual numbers of deaths there, British and African researchers said on Monday.
The strain, a variant of Salmonella typhimurium, is named ST313. Its genome was decoded by researchers from the Wel... Read More
